Week 10: Pulling from Database

Thoughts of the week

This week, I have started to work on pulling the data from the MongoDB database and storing it locally on the device. This will ensure that if the user goes on and has a bad reception, the data stored on the device will be used instead of giving the user nothing. I want an automatic refresh later, so periodically, it will check for new data and update the local data if connection permits. I will have to be careful about this as if the user is in the middle of a workout, don't change anything until after they are actually done.

Local Data Storage Implementation

To store API data locally within my app:

• I used UserDefaults for local storage
• Apple offers other persistent storage options like CoreData and FileManager
• I chose UserDefaults because:
It's simple to implement with minimal setup
Perfect for storing moderate amounts of data
Built into iOS without extra dependencies
Automatically handles data persistence between app launches
• I stored the data by:
Converting API objects to Data using JSONEncoder
Saving the encoded data with unique keys in UserDefaults
Loading and decoding the data when needed using JSONDecoder
Tracking when data was last updated with a timestamp

Next Steps

Implement User UI and store their personal workouts.
